Pancreatic cancer is a devastating disease with a poor prognosis. It ranks as the fourth or fifth most common cancer in men and women and has the lowest 5-year survival rate. Therefore, there is an urgent need to develop novel therapeutic agents for pancreatic cancer. Longikaurin E (LE), which is derived from the traditional herbal medicine Rabdosia(More)
In this study, we investigated the neuroprotective effects of asiaticoside, a triterpenoid saponin isolated from the Chinese medicinal herb Centella asiatica, in the rats model of Parkinsonism induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Rats were first injected with MPTP. One day after surgery, asiaticoside was administered and the(More)
In this study, we investigated the neuroprotective effects of madecassoside, isolated from the Chinese medicinal herb Centella asiatica, in the rat model of early phase of parkinsonism. During intragastric administrations of madecassoside for 7 days, the rats were injected with MPTP on the 7th day. And for the following 14 days, madecassoside were also(More)
Magnolol is the main constituent identified in the barks of Magnolia officinalis, which has been used for the treatment of mental disorders including depression in China. In this study, we investigated the antidepressant-like effect of magnolol, and its possible mechanisms in rats subjected to unpredictable chronic mild stress (UCMS). High performance(More)
ETHNOPHARMACOLOGICAL RELEVANCE Zhen-Wu-Tang (ZWT), the modified formulation of a classical Chinese prescription from "Treaties on Febrile Disease", was clinically employed to treat Parkinson's disease. AIM OF THE STUDY To investigate the neuroprotective effect of ZWT on intra-striatum injection of MPTP-induced Parkinson's disease in rats. MATERIALS AND(More)
AIM OF THE STUDY Traditional Chinese medicine Zhen-Wu-Tang (ZWT) is a well-known PentaHerbs formula from "Treatise on Febrile Disease". This study is to elucidate its neuroprotective effect and mechanism of ameliorative effect of the syndrome of Parkinson's disease (PD). MATERIALS AND METHODS The ameliorative effect of ZWT on symptom of PD through(More)
A series of 3'-aminospiro[indoline-3,1'-pyrazolo[1,2-b]phthalazine]-2,5',10'-trione derivatives have been synthesized by a one-pot three-component reaction of isatin, malononitrile or ethyl cyanoacetate and phthalhydrazide catalyzed by piperidine under ultrasound irradiation. For comparison the reactions were carried out under both conventional and(More)
Chaihu-jia-longgu-muli-tang (CLM) has been used for treating depressive disorders for thousands of years in China. In the present study, we investigated the antidepressant-like effect of the saponins extracted from CLM (SCLM) in rats subjected to unpredictable chronic mild stress (UCMS). The ameliorative effect of SCLM on symptom of depression through(More)
An improved synthesis of multifunctionalized pyrrolo[2,3,4-kl]acridine derivatives with different substituted patterns using silica sulfuric acid (SSA) as a heterogeneous catalyst under microwave irradiation conditions was developed. The reaction could be conducted by using readily available and inexpensive substrates within short periods of 12-15 min.(More)
A series of chalcones a1-20 bearing a 4-OMe groups on the A-ring were initially synthesized and their anticancer activities towards HepG2 cells evaluated. Subsequently, a series of chalcones b1-42 bearing methoxy groups at the 2' and 6'-positions of the B-ring were synthesized and their anticancer activities towards five human cancer cell lines (HepG2,(More)
